She grabbed Lisa's hips in her hands to draw her close and began rapidly fucking Lisa's pussy with her tongue.She grabbed Lisa's hips in her hands to draw her close and began rapidly fucking Lisa's pussy with her tongue. She thrust her tongue into Lisa's cunt, and then spread it flat on her pussy and licked the lips from bottom to top, rubbing her taste buds over Lisa's swollen clit. They were both so engrossed in the extreme pleasure they were feeling they didn't realize that Billy had come home and was peeking around the door. Billy had planned to stay at Tim's longer, but Shelly, Tim's girlfriend, had showed up and wanted to go to the movies alone with Tim. Billy packed up and came home. When he entered the house he threw down his bag and sneaked up the stairs thinking Cindy might still be sprawled on her bed asleep. He was hoping to get another peek at his older sister's sexy body. Billy had just turned 15, and still hadn't had much luck with the girls. Most of the ones he knew were interested in the older guys that had cars. As he approached Cindy's room he heard noises and noticed the door was ajar, so he stepped very softly. He could hardly believe his eyes when he peered carefully around the door. He was looking directly at his sister's cunt. She was lying naked on the floor near the door with her legs drawn up and her knees spread out. He had never seen a pussy wide open like that before, and it really excited him. Cindy's pretty friend Lisa, was also naked and was straddling his sister's breasts with her back toward Billy. Neither girl could see him. Lisa's had her hand on Cindy's crotch and he could see the finger plunging into his sister's juicy, open pussy. Cindy was making fucking motions with her hips to drive the finger deeper. He knew Lisa's pussy must be right in his sister's face and from the motions he was sure Cindy was fucking Lisa's pussy with her tongue. Even in his dreams, Billy had never imagined seeing his sister like this, and it made his cock throb wildly in his jeans. Lisa was pushing her pussy against his sister's mouth, her red hair swaying as she moved. He could hear the girls moaning as they stimulated each other's pussies. Billy grabbed at his throbbing cock through his pants and squeezed it hard. Billy had masturbated many times after only catching glimpses of Cindy's panties or breasts. Now her naked pussy was spread wide only a few feet from him, and he could see every detail as Lisa's fingers slid in and out all slippery with his sister's gravy. |
